Etabs Shell joints

[gbun617]

Hi Everyone,

Fairly new to etabs and am having a few issues.

Main issue is my slab (Shell thin, with property modifiers to make it a one way slab) is outputting joint restraints at each mesh cell.

I have tried fiddling around with selecting and deselecting the add restraint option but to no avail.

Below is an image of my output.

It's due to how the calculation approximations work (very soft springs at each node) associated with the Non-iterative Based on Mass P-Delta option.

Suggest adopting the proper iterative P-Delta setting .
